Vehicle headway distance control

摘要

A vehicle headway distance control apparatus (3) is provided with a first deceleration (±*1) control system for controlling the deceleration of a vehicle according to a distance (L) between the host vehicle and a preceding obstacle, and a second deceleration (±*2) control system, which is different from the first deceleration control system and which controls the deceleration of a vehicle according to the same distance (L). A driver operable selection section (8ˆ¼13) is configured to allow a driver to arbitrarily turn "on" and "off" each of the first and second deceleration control systems, but prohibit simultaneously operation of both of the first and second deceleration control systems.
